YOZONETECH PTFE SELAS and RODS

Due to the corrosion resistance defects of materials such as rubber, glass and metal alloys, it is difficult to meet the environment where temperature, pressure and chemical media coexist under harsh conditions, and the losses caused by this are quite amazing. PTFE material has corrosion resistance and has become the main corrosion-resistant material in petroleum, chemical, textile and other industries. Its specific applications include: conveying corrosive gas pipelines, exhaust pipes, steam pipes, rolling mill high-pressure oil pipes, aircraft hydraulic systems and cold-pressing systems, high-pressure and low-pressure pipes, distillation towers, heat exchangers, kettles, towers, tank linings, valves And other chemical equipment. To

　The performance of YOZONETECH seals has a great influence on the efficiency and performance of the entire machine and equipment. PTFE material has the characteristics of corrosion resistance, aging resistance, low friction coefficient, non-stick, wide temperature range, and good elasticity. It is an ideal choice for manufacturing seals with high corrosion resistance and temperatures above 100 degrees Celsius. Such as machines, heat exchangers, high pressure vessels, large diameter vessels, valves, pump tank flange seals, glass reaction tanks, flat flanges, large diameter flange seals, shafts, piston rods, valve stems, worm pumps, levers Seals, etc.

Excellent performance of Teflon tube

　1. Heat resistance. Polyethylene pipe deforms at 150 degrees Celsius, while Teflon can withstand instantaneous temperatures of 280 degrees Celsius and 320 degrees Celsius.

　2. Corrosion resistance. Polyethylene pipe is resistant to oxidizing acid, and Teflon pipe is more resistant to corrosion than acid and alkali.

　3. Flame retardant. Teflon tubes can ignite and spontaneously ignite; Teflon tubes are not easy to burn, difficult to ignite, and extinguished once the flame is extinguished, because they are flammable when the oxygen content is greater than 95%.

　4. For a penny price commodity, Teflon pipes are more expensive than polyethylene pipes.

　Teflon tubes are mainly corrosion-resistant and high-temperature materials. For example, heart bridge surgery will work, and some demanding food industries will also be used for packaging.

Teflon (PTFE) use conditions: industrial chemical, petrochemical, oil refining, chlor-alkali, acid, phosphate fertilizer, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous metal smelting, steel, atomic energy and polymer filter materials, high Purity product production (such as ion ion electrolysis), viscous material transportation and operation, and food and beverage processing and production departments with strict hygiene requirements.

About PTFE rod:

1. Teflon rod material: soft materials are prone to elastic or plastic deformation due to their pre-tightening force, thereby blocking fluid leakage channels, which is conducive to sealing; however, soft materials usually cannot withstand the impact of high-pressure fluid. The corrosion resistance, heat resistance and density of the gasket material have a certain influence on the seal.

  2. Teflon rod sealing medium temperature: The temperature of the medium fluid directly affects the sealing performance of the gasket, so the material must be equal to or higher than the temperature of the field working condition: In addition, temperature changes will directly affect the sealing performance of the pad, causing leakage.

  3. Teflon rod medium: The function of sealing is to seal the medium to prevent leakage. In order to better play the sealing effect, the temperature, pressure, PH value, corrosion and other factors of the medium must be considered.

  4. Teflon rod sealing surface size: the larger the contact width between the gasket and the sealing surface, the longer the path required for the medium fluid to leak, but under the same pressure, the larger the contact width, the sealing rate will decrease. Therefore, an appropriate contact width should be sought according to the material conditions of the seal.

  5. Teflon rod sealing surface conditions: The shape and surface roughness of the sealing surface have a certain influence on the sealing, and the smooth surface is good for sealing.

  6. External conditions of the Teflon rod: Vibration of the piping system, deformation of the connecting parts, deviation of the installation position, etc. will generate additional force on the seal, which will adversely affect the seal.
